ABSTRACT
Background/Objective: Sleep insufficiency, which affects more than 45% of the world's population, has a great importance when considering older adults. Thus, this research tested a mediation hypothesis, through a path analysis, which explains how depression relates to the quality of life considering the effects of sleep quality in older adults. Method: A sample of 187 community-dwelling Portuguese older adults answered questionnaires about sociodemographic status (age, gender, highest level of education completed, family status, sports activities, health, and retirement status), quality of life, sleep quality, and depression. Descriptive and path analysis statistics were performed considering the results of the normality test. Results: The sample has health characteristics and presents adequate sleep duration. Sleep quality acted as a mediator between depression and the quality of life in older adults, considering the variation of gender and health. This suggests that it is important to establish self-care practices, namely sleep quality, to intervene in the ageing process. Conclusions: It is important to consider sleep quality associated with depression for older adults and to test interventions to minimize health impacts. Also, more researches are needed about the primary prevention in sleep quality relating to depression.

Por lo tanto, esta investigación probó una hipótesis de mediación, que explica cómo la depresión se relaciona con la calidad de vida, considerando los efectos de la calidad del sueño en adultos mayores. Método: Una muestra de 187 ancianos portugueses residentes en la comunidad respondió a cuestionarios sobre el estado sociodemográfico (edad, sexo, nivel educativo más alto, estado familiar, actividades deportivas, estado de salud y jubilación), calidad de vida, calidad del sueño y depresión. Se realizaron estadísticas descriptivos y de análisis de trayectoria, considerando los resultados de la prueba de normalidad. Resultados: La muestra presenta características de salud y una duración adecuada del sueño. La calidad del sueño actuó como mediador entre la depresión y la calidad de vida en adultos mayores, considerando la variación de género y salud. Conclusiones: Es importante considerar la calidad del sueño asociada con la depresión para adultos mayores y realizar intervenciones para minimizar los impactos en la salud. Además, se necesitan más investigaciones sobre la prevención primaria de la calidad del sueño relacionada con la depresión.

Sleep health is a new and important concept. Considering the need to expand the research on sleep from the health perspective, this research proposes to validate a Sleep Health Scale (SHS) for use with the Portuguese adult population. A sample of 540 community-dwelling adults aged 18-90 years old was included. The SHS scores ranged from 0 to 30 with a mean of 19.09 (SD ± 6.49). The distribution indicated that all socio demographic variables (age, gender, and literacy) influenced sleep health. Exploratory factor analysis (EFA) demonstrated one factor for this measurement model with poor indices (Chi-square (df) = 55.02(9), p < 0.001). Confirmatory factor analysis (CFA) was performed on the single factor and showed a well-adjusted model except for question 5 (Chi-square (df) = 11.443(4), p = 0.022; RMSEA = 0.084; CFI=0.99; GFI = 0.98; AGFI = 0.94), the convergent validity (AVE = 0.55) and reliability values (α = 0.85 /CR = 0.86) were good. In conclusion, the Sleep Health Scale (SHS) is valid and reliable for the assessment of the several sleep health indicators of Portuguese adults. An investigation on the relationship between sleep health and well-being in promoting quality of life with this scale is recommended for future research.
